1. Don your dancing shoes
I would order every citizen to gather in Ruby Leung Town Square and line-dance to The Lion King and Hannah Montana soundtracks.
Then we would have a Grease sing-a-long. Rock 'n' roll is definitely here to stay in Ruby Leung Land.

2. Stadium scene
If I had my own country, I would ask my citizens to gather at Elise Choi Stadium at 6am to sing the national anthem. Hopefully that would instil some national pride in them!

3. Rest up
I would order a day of rest. Food, drinks, shelter, and all other basic needs would be met. I think mass celebrations with flag-raising ceremonies are useless, because they don't address the real problems countries face.

4. Colours and sparks
As I'm originally from India, my country's national day would combine India's two most enjoyable festivals: Holi, when people smear each other with paint and have water fights, and Diwali, the festival of lights, which involves the lighting of lamps, fireworks and sparklers.
I would combine the throwing of coloured powder with the beautiful fireworks to create a truly unforgettable National Day celebration.

5. Jelly joy
My country would be called Jellya. I would celebrate National Day in houses made from jelly, and there would be a huge feast of jellies. I love jelly!

6. Sleep well, people
Sleep! No, it's not a joke. Catching up on some sleep would make my citizens more efficient in the long run.

7. A new high
I would climb the highest mountain in my country. Why? It doesn't cost any money, and mountain climbing is my favourite sport. When I reached the highest point, I would sing the national anthem so that everyone could hear me!

8. Song for everyone
National Day would be on my birthday, December 29. On that day, pictures of me would be plastered everywhere and I would sing a song to entertain the citizens.

If I had my own country, I would organise a sleeping competition because relaxing is always the best reward for hard-working people.

10. A crazy time
I wouldn't just have a one-day holiday; it would be a week-long "festival". There would be no homework for kids, and people would be able to eat as much as they want. Children could boss adults around, too, and would have permission to do anything. Mwahahaha!

Chung Yeung Festival is celebrated because of the belief that the ninth day of the ninth month in the lunar calendar (October 13) could be a dangerous date.
